+The contouring algorithm is very simple to implement. Just follow the instructions of the method. Still our contour was not very smooth. It had sharp edges
+everywhere and there was no smooth curve in the contour. The problem was with the intersection with the isovalue. We did'nt exactly follow the equation that was in
+the study material. When we reverted to that equation the isolines where nice and smooth. \\
